Machining Level I - Turning Operations: Turning Between Centers
Credential: Machining Level I - Turning Operations: Turning Between Centers
Credentialing Agency: National Institute for Metalworking Skills, Inc (NIMS)
The Machining Level I certification identifies and recognizes Machinists with skills applicable to the specific metalworking process and level of competency. Machining Level I certifications are offered in nine different machining skill cluster areas, each of which allows an individual to focus on skill sets that are most important to their job or career objectives. These skill cluster areas are Job Planning, Benchwork, and Layout, Vertical Milling, Drill Press, Surface Grinding, Turning - Between Centers, Turning-Chucking, CNC Milling, and CNC Turning. Earning a NIMS certification requires the successful completion of both a performance and written examination. The performance exam will be the manufacturing of a part, the set-up and operation of a machine or the writing of a program that will manufacture a specific part. There are performance assessment requirements for all skill cluster areas except Measurement, Materials, & Safety Skills. One written exam is available for both Turning skill cluster areas (each turning area has a separate performance assessment).
More information can be found on the certifying agency's website.
